Do troughs tend to bring stormy weather?

Yes. A trough is an elongated region of low atmospheric pressure, usually depicted by a dashed orange line on a weather map. Low surface pressure often indicates upward motion in the atmosphere, which can be associated with cloudy or stormy weather occurring along and east of the trough axis. Pressures are higher west of the trough, indicating sinking motion in the atmosphere, which usually prevents clouds and precipitation from forming.
